5 tain new and useful Improvements Carbu- ,reters, ofwhich the following isa specification. My invention relates to certain new and .useful improvements in machines for carvbureting air with gasolene for producing a gas for illuminating and other purposes, and in its genericnature the invention comf prises a gasometer having provisions for exposing the gasolene to a current of air set in 1 5 motion by a fan, means for continuously su plying the gasolenefrom 'a reservolr to t 1e' exposedportions of the vaporizing chamber where 1t canlcome into contact W1th the alr and become vaporized, and means for maln- `ZOtaining a constant air current together with means for. simultaneously operating both the gasolene elevator and the fan.

`Again, my invention has for its object to provide-a su` plemental air feeding device, by

means of W lch the gas 'generated maybe diluted, if desired, to make it suitable for its retuir'ed use.

n its more`detail nature, the invention embodles certain novel detalls ofconstruction, combination and arrangement of parts,

' all of .which will be first described'in detail' and then be specifically pointed out in the `appended claims, reference being had to the accompanying drawings, in Whch:--

Figure 1, is a perspective view of my invention. Fig. 2, is. a central vertical longitudinal`section of my invention. Fi 3, is avertical section on the line 3 3 of gig. 2. Fig.

`4, is a horizontal section on the line 4-4 of A 40 Fig. 2. Fig.4 5, is asimilar viewon theline 5-`5 of Fig. 2. Fig.,6,- 1s a rearelevation .partly in section.

VReferring now to theaccompanying drawyin s, in ywhich like letters and numeralsof re erence indicatelike parts in all ofthe figures, 1 ldesignatesthe casing which is mounted over the blower mechanism '2,' which blower mechanism includes a rotary fan 2, and the blower casing 2b in which the fan shaft 2 is journaled, the shaft 2 projecting..

, to the outside Vof the casing and'v carrying a Windlass 3 having a-crank 3*, byV means of ywhich it maybe turned.V The windlass 3is fadapted to receive a cable .4 whichpasses over an idler pulley 4a .and is attached to a weight 5, for a pur ose which will presently appear. The wind ass 3 includes a sprockete wheel 3b aroundv which the drive belt or chain 6, for the elevator passes. The casing 'which is divided into three chambers has an upper chamber 1.x, intermediate 1y and lower chamber lz, the lower chamber lz being di-l i vided into supplemental chambers by the horizontal partitions 8 and 9, the partitions 8v and 9 having oppositely disposed openings 84911, whereby communication may be had between the various sections of the lower compartment 1. The lower compartment 1z above the partition 8 is in communication with the intermediate chamber 1y, through a 'funnel 10 that has an outlet preferably formed of a perforated surface lOto discharge against a erforated nozzle 11B' of a supplemental air flied pipe 11 controlled by a va ve -1-11D and in communication withlthe main air pipe 12, adjacent tothe blower casing 2b.

The under walls of the partitions 8 and 9 are provided with V-shaped baffles Sli-9X. which extend nearly the entire'ldistance between the partitions and the next adjacent wall surface, the baffle 85 extending nearly to the lpartition 9, while the baffle QX-,eXtends nearly to a supplemental partition 9y which forms the top of the gasolene'chamber 20.

Gasolene is'. admitted to the chamber 20 through an inlet pipe 20, closed by a' cap 20h, as indicated, or in anyy other approved manner. The bottom Wall 13 of thechamber 1y is provided, on its under surface, with a baille 13x similar. in form to. that of the baflle 8x, but dis osed oppositely therefrom and spaced near y to the partition 8. The gas is taken off through an outlet ipe 14, fromthe chamber 1y, a screen 14l o line gauze Wire being stretched across the chamber 1y over the outlet 14 to act as a ltering medium.

15 designates a gasometer bell, which p rojects into the chamber 1x of the machine and 1s Water sealed as at 15x, limiting chains or cables 15y being provided 'to limitv the move ment of the bell 15.A I f l The air pipe 12-has its. entry end 12a in communication .with "the ,blower casing 2b and passes upcentrally throughthe cham` 4and spaced therefrom to provide areturn pass in the direction of the arrows in Fignl,`

between the partitions 93', 9 and 8, allowing the gasolene to become thoroughly vaporiaed and any excess gasolene that. should become condensed will 'deposit upon the partitions 8,

, Q and 9y and vfiow back into the gasolene tanlr` 20, unlosssooner again vapori'zed by the passing' current-of gasolene and air., From the top of the chamber liz the vaporized'gasolene 'and' air passes'th'roughthe perforated outlet of thefunnel 10 into the chamber 1y from whence the gas may be drawn through the outlet' pipe 14 and delivered to the illuminating system. Should vit be found that the gas l"delivered through the pipe y14 is too rich in gasolene, additional air may be admitted into the chamber 1y byopeningthe valve 1'1" 'in the supplemental air pipe 11 and permitting the air to be discharged into the chamber 1y through the perforated nozzle, in finely divided streams to cause an intimate mixture between the vaporized gasolene in the chamber '1 Y and suchair. y In order that lthe gasolene may be 'maintained on the up er surfaces of the partitions 8,9 and 9Y and flp 8 back into the gasolene tank 20, I provide an elevator -21 which consists of an endless chain of-buckets 21 a passed over idler pulleys 2lb on shafts 21C, the lower shaft 21c being arranged so that the buckets 21 a will di )into the gasolene in the chamber 20 ywhi e the upper shaft 21c is arranged so that the buckets 21a will discharge their contents onto the baiiie 22, from which the gasolene flows through the slot 22x in the vertical partition `22y onto the partition 8 and from thence ercolates downward until the excess gasoibne reaches the gasolene chamber 20. The vertical partition 225 extends fromthe partition it, y

13 down to near the bottom of the gasolcne Y chamber leaving a space between itself and the bottom of the gasolene chamber to allow the gasolene to maintain the same level in the gasolene chamber asin the elevator compartment.

In order that the blower 2a may' be operated simultaneously with the elevator 2 and vice versa, one of the elevator shafts, say the lower shaft 21, projects to the outside of the casing and carries a sprocket or pulley 6X, around which the 'endlessl belt or chain `6 passes.

So far'as described, the'manner` in which this invention operates, will be best eX- plained as follows: Assume the gasolene ow from the upper partition chamber 20 to have been filled with gasolene and the pipe 20a closed, the operator desires to generate carbureted air during a predetermined pcriod for, say, illuminating or other similar purposes. The cable 4 having been previously wound up on the wiudlass 3, with the weight 5 at the top the operator releases the shaft 2c to permit the weight 5 to operate the windlass (any suitable governor mechanism and lock device for holding the members inoperative at times may be provided, as the.

lene` yAt the same time the elevator 21 iscarrying the gasolene from the chamber I20 and depositing it on the partition 8 from which it Hows down to the chamber 20 and onits way more or less of it is vaporized by th'epassing air current (see arrows in Fig. 2) andthe vapors of gasolene and air pass through the funnel 10 in the chamber 1y and from thence to the supply pipe 14 from lwhich the vaporized` fluid maybe withdrawn` and used. Should any unevenness of the fan and elevator occur so that the elevator does not run steady, the bell 5 through its action will serve to maintain a steady -current through the passage 16a to the gasolene, from thence into the chamber 1V, it being understood that the chambers 1X and 1y are notin direct communication with one another.A y
